I fixed the jamming problem on mine. The jamming problem is actually related to the magazines. Some of the magazines have weld pits just under the feed lips that can snag the rims of the 7.62x54R cartridges, resulting in the nose of the round turning down and slamming into the front of the mag. A bit of work with a file and the problem goes away.
I like mine. Nice rifle. Was well-finished and well-built. I can't tell you how accurate it is, though, because I had issues sighting in with the factory scope (I lack a good benchrest to really make it possible, and I'm left-handed) and am in the process of rescoping it. The current PSL's coming in are very nice rifles, and are effectively mil-spec. The only thing different from the military model is the trigger group (factory-installed) and the ground-down bayonet lug.
Bottom line: Century just imports them now, and doesn't monkey them up. Some of the earlier PSL's required modification, but now they're made to importable specs by the original factory. The new ones coming in are much more accurate, and very nice guns. The people who had bad results with earlier PSL's likely wouldn't see the same if they purchased one now.
